加油站计量监督管理系统的Petri网建模与设计

摘要

In view of the problems of gas stations' weak management,short scales,tanker measurement cheat and the measurement personnel neglected their duties,engaged in malpractices for selfish ends.This paper proposed a metrological supervision and management system for gas stations based on Petri net.The system used the Linux operating system and ARM9 S3C2440 as the slave collection computer system,ZC301p camera as image sensor,Wi-Fi wireless communication sending the collect image information to remote monitoring terminal.Host computer was based on ASP.NET and SQL Server database technology,it developed with B/S structure and introduced the Petri net work tool to analysis and modeling the system.The results show that the system strengthens the measurement management of gas stations and plays a strong role in the supervision of public opinion.It maintains the economic order and the legitimate rights and interests of consumers.%针对加油站存在管理混乱、短秤少量、加油机计量作弊和计量人员玩忽职守、徇私舞弊等部分问题,文中提出了一种基于Petri网的加油站计量监督管理系统.该系统采用Linux操作系统与ARM9 S3C2440作为下位机采集系统,将中芯微ZC301P摄像头作为图像传感器,利用Wi-Fi无线通信将采集到的图像信息发送至远程监控端.上位机基于ASP.NET和SQL Server数据库技术,采用B/S结构开发并引入Petri网工具对系统进行需求分析和建模.结果表明,该系统加强了加油站的计量管理,充分发挥了国家和社会舆论监督强势,维护了零售成品油市场经济秩序和消费者的合法权益.
